Abstract---.NET Framework is a software framework deployment, Security, Portability. Custom attributes are one developed by Microsoft that runs primarily on Microsoft of the most innovative features of the .NET framework [2]. Windows. It includes a large library and provides language The Fig 1 shows the .Net Framework stack. interoperability (each language can use code written in other languages) across several programming languages. II. NET FRAMEWORK 2.0 FEATURES Programs written for .NET Framework execute in a software environment, known as the Common Language Runtime A. ADO.NET (CLR), an application virtual machine that provides services New features in ADO.NET include support for user-defined such as security, memory management, and exception types (UDT), asynchronous database operations, XML data handling. The class library and the CLR together constitute types, large value types, snapshot isolation, and new .NET Framework. When the new versions of .Net attributes that allow applications to support multiple active framework are release it overcomes the problem of early result sets (MARS) with SQL Server 2005. .NET framework version and add new features in its which provide better is a rather radical approach to make the development of usability of it. Windows more component-oriented [4]. Keywords: Framework, Compatibility, Extensibility, B. ASP.NET ADO.Net, Interoperability. The Microsoft .NET Framework 2.0 includes significant enhancements to all areas of ASP.NET. For Web page I. INTRODUCTION development, new controls make it easier to add commonly .NET Framework's Base Class Library provides user used functionality to dynamic Web pages. New data controls interface, data access, database connectivity, cryptography, make it possible to display and edit data on an ASP.NET web application development, numeric algorithms, and Web page without writing code. An improved code-behind network communications. model makes developing ASP.NET pages easier and more robust. Caching features provide several new ways to cache pages, including the ability to build cache dependency on tables in a SQL Server database. It is possible to use Frame Oriented Programming in Metadata [3]. ASP.NET accommodates a wide variety of browsers and devices. By default, controls render output that is compatible with XHTML 1.1 standards. You can use device filtering to specify different property values on the same control for different browsers. C. .NETRemoting .NET Framework Remoting now supports IPv6 addresses and the exchange of generic types. The classes in the System.Runtime.Remoting.Channels.Tcp namespace support authentication and encryption using the Security Support Provider Interface (SSPI). Classes in the new System.Runtime.Remoting.Channels.Ipc namespace allow applications on the same computer to communicate quickly Fig. 1: .NET Framework Stack Structure. without using the network. Finally, you can now configure Programmers produce software by combining their own the connection cache time-out and the number of method source code with .NET Framework and other libraries. retries, which can improve the performance of network load- balanced remote clusters. .NET Framework is intended to be used by most new applications created for the Windows platform. Microsoft D. XML also produces an integrated development environment The new System.Xml.XmlReaderSettings class allows largely for .NET software called Visual Studio. The feature specification of the type of verifications to be done when of reflection is provided in .Net Framework [1]. The General using a subclass of XmlReader to read XML data.
